Disassemble Old Differential and Mount Ring Gear to New Differential

What happens here

The old differential carrier is placed on a workbench. The bolts holding the ring gear to the carrier are removed, typically by hammering them out after partially threading them to protect the threads. The ring gear is then carefully separated from the old carrier. The new Posi unit (limited-slip differential) is prepared by cleaning its surface, and the old ring gear is then installed onto the new Posi unit. This involves aligning the bolt holes and ensuring a flush fit.

Goal: Transfer the ring gear from the old to the new differential.
